After the iPad 3 became available late last week several users informed me of a bug on the iPad 3 making Knots 3D unusable. We worked on a fix over the weekend and have submitted it to Apple for review and approval. It typically takes Apple about a week to approve new releases and updates so hopefully the latest version of Knots 3D including the Retina Display bug fix for iPad 3 should be available around March 26. I have asked Apple to expedite the fix so it may possibly be available before that. The good news is the release also includes over a dozen new knots along with the fix including: Alpine Butterfly, Truckers Hitch, Palomar Knot, and more.
Thanks for your patience and understanding.
